How do you stay consistent with a workout routine?

I’ve been trying to become more consistent with exercise, but I find it difficult to stick with the same routine for more than a few weeks. I’m curious how other people approach this, especially those who have busy schedules. Do you prefer working out alone, following an online program, or getting guidance from a Fitness trainer? I think having someone who can adjust workouts based on your goals and keep you accountable could make a difference. For those who have worked with a trainer, did it actually help you stay consistent, or did you eventually prefer managing your workouts on your own?
